Nelson Johnson discusses Behavior Driven Development (BDD) and how to implement it for testing Dynamics 365 applications. BDD uses structured English phrases to invoke test-driven development functions and makes it easier to involve end users. The document provides an example of a BDD test written in Gherkin and outlines the tools and steps needed to set up a BDD framework for Dynamics 365, including Visual Studio, SpecFlow, and Selenium.

What is Behavior Driven Development (BDD)
• Framework for software testing
• Abstraction layer on top of typical Test Driven Development
• Uses structured English phrases to invoke TDD functions
• Gherkin Language (https://cucumber.io/)
• User defined – very flexible

Why BDD
• Makes it easier to involve end users to develop tests
• Added transparency between requirement and test
• Separates user behavior from test implementation
• Utilizes dev-ops methodologies for higher business value
• Increases turnaround time
• Build Verification Testing
• CRM Upgrade Testing
• There is a downside
• Can take a long time to run
• Complex logic may be difficult to verify

How easy is it to learn Gherkin?
Feature: SearchByPhone_PhoneCall
As an end user I need the ability to
search for contacts by phone number
@SearchByPhoneNumber
Scenario: Return Login Only
Given I log into CRM
When I navigate to Sales to get to Activities
When I click on Phone Call
And I set field phonenumber to '2369874125'
Then Check the value of lookup field bpt_callercontact to see if it is 1 Login Only Phone
